Co-Founder (Food Science / Animal Nutrition)

Co-Founder (Food Science / Animal Nutrition)

Swiss Fresh Pet Food Venture

The short version: We're building Switzerland's first industrial fresh, chilled pet food platform. The pilot is done – 8,000+ meals produced, real customers, strong unit economics. Now we're looking for a co-founder with a food science or animal nutrition background to take this to the next level. What exists: A validated product (fresh, chilled pet meals for dogs & cats – not frozen, not dry). A strategic production & logistics partnership with one of Switzerland's largest food corporations. Proof of concept: 8,000+ meals produced. 300+ early supporters from a crowdfunding campaign. A clear path to CHF 600-850M domestic market with zero industrial fresh competitors What's missing: A co-founder who brings deep expertise in food technology, food processing, or animal nutrition – ideally with a current or recent connection to a Swiss university or research institution. Someone who is excited about building the R&D backbone of a category-defining brand. What you'd own: Product development & formulation strategy / Research partnerships with Swiss academic institutions / Process optimisation (pasteurisation, HPP evaluation, shelf-life extension) / Nutritional validation & regulatory compliance What makes this interesting: The product works and customers love it – this is not an idea on a napkin / Strategic infrastructure partner already committed (production, logistics, funding) / Fresh pet food is a CHF 12B+ global market growing 15%+ per year / Switzerland has no industrial player in chilled fresh pet food – wide open space! Who you might be: MSc or PhD in food science, food technology, animal nutrition, or related field / Currently at or recently graduated from a Swiss university (ETH, ZHAW, BFH, EPFL, or similar) / Entrepreneurial mindset – you want to build, not just research / Comfortable with ambiguity and early-stage speed / Bonus: experience with HPP, thermal processing, or pet food formulation Next step: Reach out with a few lines about yourself. Happy to share more details over a coffee or call. No formal application needed – just genuine interest.

Founding AI Engineer for early-stage, London-based, VC-backed startup

Founding Applied AI Engineer

Most “AI agent” roles are prompt engineering with better branding. This isn’t one of them. We’re building agents that actually operate inside live games: - Reason over images and video across frames - Decide what to do next in messy, shifting UIs - Tap, swipe, navigate, recover from failure - Run reliably across devices, lag, edge cases No fixed scripts. No demo theatre. Production systems that studios trust more than manual QA. You’ll take our proprietary VLM and turn it into a real-world decision-making system. Think less “clever prompts” and more autonomy, control loops, failure handling, systems design. If you’ve built: - Vision-based agents - Robotics / autonomy systems - Complex UI automation that had to survive the wild - Production ML systems where reliability actually mattered We should talk. Founding-level ownership. Early traction. Real customers. *Please note that this role requires you to be based in London, UK.
